What products will most likely be observed in a combustion reaction?

Oxides, and water (and water is an oxide of hydrogen).

Explanation:

Typically we combust hydrocarbons; certainly, we do so in order to make our goggomobiles go.

If we represent petrol or diesel as hexanes:

${C}_{6} {H}_{14} \left(l\right) + \frac{19}{2} {O}_{2} \left(g\right) \rightarrow 6 C {O}_{2} \left(g\right) + 7 {H}_{2} O \left(l\right)$

Of course combustion is never complete in an internal combustion engine; some products of incomplete combustion result, i.e. $C O$ and particulate $C$.

${C}_{6} {H}_{14} \left(l\right) + 8 {O}_{2} \left(g\right) \rightarrow 4 C {O}_{2} \left(g\right) + C \left(s\right) + C O \left(g\right) + 7 {H}_{2} O \left(l\right)$

Are mass and charge conserved in these reactions? If not, they should be!
